To (all, whom it may concern.-

Be it known that we, CARL EMIL POIGNANT and GUST CARLPoIGNANT,-citizensof the United States, residing at Birchlake, in thecounty of Bayfield and State of Wisconsin, have invented certain new anduseful Improvements in Vriting Attachments for Desks; and we declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to writing attachments for desks.

The object of the invention is to provide an attachment of thischaracter which may be applied to desks or writing-tables, thus forminga convenient means for holding writing or drawing paper in the form ofrolls which may be unreeled as needed.

Another object is to provide means whereby copy-paper may be disposedbeneath the writing or drawing paper, which latter will be thin enoughto permit seeing the copy beneath, and thus enable the same to betraced.

A further object is to provide means whereby aseries of strips, each ofwhich contains the letters of the alphabet, arranged in order one abovethe other, said strips being adapted to be wound in either direction tobring the letters thereon in position for spelling various words.

lVith these and other objects in View the invention consists of certainnovel features of construction, combination, and arrangement of parts,as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a top plan view of a desk orother support, showing the application of the device. Fig. 2 is an endelevation of the same. Fig. 3 is a vertical sectional view. Fig. at is avertical sectional view taken at right angles to Fig. 3. Fig. 5 is aplan view showinga modified arrangement of the device. Fig. 6 is a planview of the paper supporting plate. Fig. 7 is a top plan view of amodified form of the device. Fig. 8 is a side view of the same, and Fig.9 is a longitudinal vertical sectional View through the same.

Referring more particularly to the draw-- ings, 1 denotes a supportingboard or table, which is here shown as being the top of a desk. In saidboard or table is formed a rectangular opening 2, over which is arrangeda paper-supporting plate 3, having formed near its upper and lower edgestransversely-disposed slots 4 and 5. On the under side of the board ortable 1 beneath the slots t and 5 are arranged paper holding rolls 7 and8, the shafts of which are journaled in brackets or hangers 9, securedto the under side of the table. The shafts of the rolls 7and 8 extend tothe right-hand edge of the board or table 1 and have fixedly mountedthereon handwheels 10. On the Wheels 10 are arranged groovepulley-wheels 12, around which are placed an elastic belt 13, wherebywhen one of said hand-wheels is turned motion will be imparted to bothrolls to turn them in the same direction. If desired, flat springs 14may be secured to the under side of the table 1, the opposite ends ofsaid springs 14 being adapted to bear upon the hubs of the hand wheels10 toserve as friction-brakes to prevent said rolls from being revolvedtoo rapidly.

On the ro1l7 is arranged a roll of paper 15, the end of the paper beingpassed upwardly through the upper slot in said plate and across the topof the same, thence downwardly through the slot at the lower end of theplate, where it is attached to the roll 8 in any suitable manner. Afterthe paper has been thus arranged the rolls may be revolved, therebywinding said paper oh? the upper roll 7 and onto the lower roll 8, thepaper thus passing across the top or outer face of the plate 3, and bywhich means a fresh surface may be quickly brought into position uponthe top of said plate.

In the plate 3 adjacent to the slots 4 and 5 are formed similar slots 16and 17, beneath which are arranged copy-holding rolls 18 and 19. Theshafts of said rolls are journaled in hangers or brackets 20, which aresecured to the under side of the table 1 and are adapted to extend tothe edge of the table, where they are provided with hand-wheels 21,having arranged thereon pulley-wheels 22. These pulley-wheels 22 areconnected by a belt 23. WVound upon the rolls 18 and 19 is a sheet 24 ofpaper or other material, on which 18 arranged a writing or drawing copy,said sheet being passed through the slots 16 and 17 and across the faceof the plate 3 beneath the paper 15. When the copy-sheet is used inconnection with the device, the paper 15 will be suflicientlytransparent to enable the copy to be seen and traced upon the paper,thus instructing the user of the device in the formation of the writingor drawing characters of the copy. The endless belts 23, which connectthe pulleys of the rolls, frictionally engage the said pulleys and coactwith the paper on the rolls to prevent casual rotation of the latter. Asthe diameter of one roll increases, while the diameter of another rolldecreases by the rolling off of the paper, the belt, althoughfrietionally engaging the pulleys, will slip thereon from time to timeto the extent required to prevent the paper from being disrupted.

In Fig. 5 of the drawings the copy-holding rolls are in the form of aseries of independently-mounted and indepcndently-revolving rolls 25 and26, arranged in sets upon shafts journaled in brackets 20. On each pairof rolls in said series is wound a strip 27 of paper or other material,on which is printed an alphabet, the letters being arranged one abovethe other, so that when said strips are arranged side by side the rollsmay be manually grasped and turned independently of each other, thusmoving said. strips to cause the letters thereon to spell certain words,which arrangement will permit the user to compose his own copy. Thepaper strips 27 are disposed across the face of the plate 3 beneath thepaper 15 in the same manner as described in connection with thecopy-paper hereinbefore described.

In Figs. 7, 8, and 9 is shown a modified form of device. The form shownin these figures consists of an open rectangular frame 28, to theopposite end of which are hinged boards or plates 29, which are adaptedto open and close in recesses formed in the upper edges of the frame 28.Between the boards 29 is arranged aglass plate 30, said plate beingpreferably seated in rabbets formed in the upper ends of the side piecesof the frame an d is held in place in any suitable manner. Between theadjacent edges of the glass plate 30 and the boards 29 are formed slots31. Journaled in the opposite ends of the frame 28 are pairs of rollers32 and 33. The pair of rollers 32 are mounted between the rollers 33 andslightly above the same. On said rollers 32 is adapted to be wound asheet of paper or other fabric 84, on which is inscribed the charactersforming the copy. The strip of paper or fabric 34: is adapted to passthrough the slots 31 and over the glass plate, across which the samewill be. drawn back and forth when wound in either direction by therolls 32. On the rolls 33 is adapted to be wound a sheet of transparentpaper 35, which also passes through the slots 31 and over the copy-paperon the glass plate 30, so that the copy may be readily seen through saidtransparent paper and traced onto the same. By winding the copy-holdingroll in one direction or the other the characters on said paper will bebrought into proper position for tracing the same, the transparent paperbeing shifted back and forth across the plate by manipulating the rollson which the same is wound. The ends of the transparent and copy paperare secured to the rolls 32 and 33 by means of wire clips 36. On one endof the rolls 32 and 33 are formed short stub-shafts or trunnions whichengage bearing-apertures formed in one of the side pieces of the frame28, and on the opposite end of said rolls are formed shafts or trunnionswhich are adapted to be engaged with slots 37, formed in the oppositeside piece of the frame. On the shafts or trunnions at this end of therolls are formed buttons or knobs 38, by which the rolls may berevolved. In order that the rolls may be held in position and preventedfrom casually unwinding or revolving in their bearings, a coilspring 39is provided, said spring being arranged on the side of the frame and hasformed on its opposite end wire hooks 10, which are adapted to bear onand engage the trunnions of the rolls in the knobs 38 in the adjacentside of the frame. The tension of the spring 39 is exerted to causethehooks 4:0 to bear on said trunnions, thereby preventing a retrogrademovement of the rolls and holding the same in position. Pivotallyconnected to the upper end of the frame is a supporting-bracket 11,whereby the frame may be held in an inclined position to facilitate theuse of the same. By this arrangement or form of the device the same ismade portable and may be readily carried from place to place as desired.

While we have shown and described the device in the form of a writing ordrawing instructor, the primary object being to guide and train the handof the user by means of tracing suitable copy, it is obvious that thedevice may be used as a writing or memorandum tablet, in which form thecopy-holding rolls and the copy contained thereon would not be used. Theconstruction and arrangement of the device is such as to afford aconvenient means for holding paper either in the "form of a copyingdevice or as a simple writing or memorandum tablet.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood Without requiring a more extendedexplanation.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is

1. In a writing device of the character described, a frame having awriting-plate provided with openings, pairs of copy and writing paperrolls journaled in said frame and having pulleys and means for turningsaid rolls, an endless belt engaging and connecting the pulleys of thecopy-paper rolls, and an endless belt engaging and connecting thepulleys 01 the writing-paper rolls, said belts frictionally engagingsaid pulleys to prevent casual rotation of the said rolls, incombination with writing and copy paper strips having their ends partlywound on the respective pairs of rolls and their intermediate portionsin mutual contact, passed through the openings of and bearing on thewriting-plate.

2. In a writing device of the character described, a frame having awriting-plate and provided in one side with bearing-slots each open atone end, pairs of copy and writing paper rolls journaled in saidbearing-slots, and means frictionally engaging said rolls and connectingthem together to prevent casual rotation thereof and retain them in theinner closed ends of the said bearing-slots.

In testimony whereof we have hereunto set our hands in presence of twosubscribing witnesses.
